Democracy and Capitalism - What's the Difference?

I am 100% on do what people want, but I'm a minority among certainly the academic economist. He really points out this very interesting, almost dialectic in which the whole thing is actually quite fragile and that the extremes of capitalism can begin to destroy a democracy. In other words, just because they are core to each other, he doesn't say, ah ha hands off, look, it's all good.
